Basketball is a group ball sport consisting of two teams of five people each play scoring points by inserting the ball into the basket of the opponent. Basketball can be on an open field, although professional matches are generally conducted in an enclosed space. The required match field is also relatively not large, for example compared to football. In addition, the game of basketball is also more competitive because the tempo of the game tends to be faster when compared to other football sports, such as volleyball and football.
Basketball is one of the most popular sports by the population of the United States and the population in the other hemisphere, among others in South America, Southern Europe, Lithuania, and also in Indonesia. Many basketball competitions are held every year, such as the British Basketball League (BBL) in England, the National Basketball Association (NBA) in America, and the Indonesia Basketball League (IBL) in Indonesia.
HISTORIES
Basketball is considered a unique sport because it was created accidentally by a sports teacher. In 1891, Dr. James Naismith, a Canadian sports teacher who teaches at a college for professional students at the YMCA (a Christian youth college) in Springfield, Massachusetts, must make a game in an enclosed space to fill the time of the students during the winter holidays in New England. Inspired by a game he played as a child in Ontario, Naismith created the game now known as basketball on December 15, 1891.
According to the story, after rejecting some ideas because it was considered too hard and less suitable to be played in closed rinks, he then wrote some basic rules, sticking a basket on the wall of the sports arena room, and then he wrote down some basic rules, and ask the students to start playing the game of his creation.
The first official basketball game, held on January 20, 1892 at the workplace of Dr. James Naismith. Basketball is the name spoken by one of his students. This sport was soon famous throughout the United States. Fanatical fans are placed all over the branches in the United States. Match after game was held in all cities of the United States.
In the beginning, each team was nine and there was no dribble, so the ball could only move through the throw. The history of basketball rules begins with 13 basic rules written by James Naismith.
